      abstract     = {The vibrissa follicle is a complex mechanotransducer with
                      intricate accessory structures such as vibrissa, ring sinus
                      and ringwulst as well as rich innervation by diverse
                      afferent types. Establishing how afferent types and
                      accessory structures operate together to derive specific
                      kinds of sensory information has been challenging, because
                      we often lack precise information on afferent types,
                      accessory structures and vibrissa function. Here we address
                      this challenge by synchrotron X-ray imaging of vibrissa
                      follicles of rat vibrissae with distinct function.
                      Specifically, we characterize accessory structures and trace
                      myelinated axons of the all-purpose-sensing C2-, an
                      object-sensing micro-, the wind-sensing supraorbital- and
                      the ground-sensing trident-vibrissa. We find that while
                      vibrissa length and follicle size differ widely across these
                      vibrissae, the ringwulst and the associated club-like
                      afferents are of near constant diameter and height and
                      appear to form a non-scalable sensory module. The two longer
                      vibrissae (supraorbital and C2 vibrissa) have noticeably
                      more club like afferents, suggesting a special role of the
                      ringwulst in transducing presumably smaller deflection
                      angles encountered by long sensory hairs. The trident
                      vibrissa receives overall few afferents, which are strongly
                      polarized to the posterior vibrissa-shaft, a putative
                      specialization to sensing forward-egomotion. We conclude
                      that high-resolution structural analysis allows relating
                      follicle architecture and function.},
